I've been studying the pics for the better part of this evening, and it has occured to me that the new Force Unleashed Stormtroopers might be using kitbashed parts from the Concept Stormies. If you'll notice, the helmets, upper arm and leg structures are strikingly similar.
Neat idea, in any case, as I've always liked the Concept Stormie. Still, does anyone else see something here?
